Environmental Education Plus combines systemic thinking with a constructive approach to emotions, a culture of mindfulness, and everyday action. Its concept focuses on education for sustainable development while also incorporating the important aspect of personal development. This leads to comprehensive skill development, as encouraged in the Curriculum 21. The practical book guides through a seasonal cycle, where the school environment is explored holistically. Children discover animals and plants in their habitat, draw them, and learn their names, characteristics, and significance for both humans and nature. They reflect on their feelings towards these living beings, which evolve throughout the research process. Topics such as bird feeding in winter, sounds and noise, local traffic, and mobility are always approached cognitively, complemented by emotional experiences, discussions, and the initiation of responsible environmental actions.
